• 

About  tliirtv  milos  north  of  tho  city  of  B«']lt'iplle  (wiiich 

is  situated  on  Lako  Ontario),  and  in  the  township  of  Marnioi  a, 
Ont.,  is  found  a  belt  of  gohl-bearing  (juartz  veins,  wlii'-li  liave 
now  been  shown  to  contain  ininiense  (uantities  of  re  of  a 
hi^ldypi'ofitabhj  '^  :  '  tv.  Tlie  luiiKss  are  situated  on  thoMoita 
E/iver,  in  a  well-woo(h'd,  rolliu}.^,  ajfricultural  country,  ^\h<'re 
the  roads  ar<;  good  and  level,  and  the  distance  to  the  railroad, 
at  the  town  of  Madoc,  is  about  ten  niih>s,  and  to  Stirling,  on 
another  railroad,  is  about  sixteen  miles.  During  the  ])resent 
year,  it  is  expected  that  the  railway  will  be  completed  to 
within  three  or  four  miles  of  the  mines.  At  the  present  time, 
liauling  from  the  mines  to  Madoc  can  be  contracted  for  at 
from  $1.25  to  $1.50  per  ton  for  the  year  through  ;  during  the 
winter,  hauling  on  sleighs  costs  much  less  than  during  the 
summer  on  wagons.  The  cost  of  hauling  is  based  on  the  cur- 
rent rate  of  $2  to  $2.50  per  day  for  two-horse  teams,  including 
the  wages  of  the  driver  and  the  keep  of  the  horses. 

II.  Character  of  the  Veins  and   of  the  Ore. 

The  gold-bearing  veins  are  quartz-filled  true  fissures  in 
syenitic  granite,  with  micaceous  or  talcoid  slates  forming  the 
walls  of,  and  horses  in  the  veins.  This  talcose  slaty  rock  is 
clearly  the  product  of  the  chemical  decomposition  of  the 
syenite  along  the  fissure,  where  it  and  quartz  form  the  gangue 


I 


8 


for  an  arseuicrl  gokl-beariiifj:  iron  jiyrites  (mispickel).  The 
magnesia  of  the  talc  comes  from  the  horiibhnule  in  the  syenite. 
The  r.iispickel  is  found  generally  in  a  crystalline  form,  though 
sometimes  in  heavy  amorphous  masses  running  in  beds 
through  the  (piartz.  Considerable  (piantities  of  crystallized 
calc-spar  also  occur  irregularly  in  the  veins. 

Some  four  or  live  ])arallel  veins  have  been  proven  to  exist 
in  a  belt  of  500  or  GOO  feet  in  width,  running  through  the 
property  of  the  company  for  a  length  of  over  three  (piarters 
of  a  mile,  while  the  main  vein  has  been  opened  on  adjoining 
properties,  making  a  total  ])roven  length  of  this  great  fissure 
of  about  three  miles  on^tlif  vein,  a  fact  which,  next  to  actual 
sinking,  may  be  considered  the  best  proof  of  the  continuance 
in  d(>])th  o^tJie  veins.  Tliree  of  these  veins  have  been  proAcn 
on  this  property  by  costine  pits  and  shafts  sunk  at  short 
intervals  along  tlnur  outcrops,  to  depths  varying  from  15 
to  150  feet.  In  this  manner,  the  east  or  main  vein  has 
been  thoroughly  explored  over  a  length  of  aboUt  800  feet  by 
shafts  of  from  40  to  150  feet  in  depth  ;  these  have,  in 
every  case,  been  in  pay-ore  all  the  way  ;  their  lowest  points 
are  now  in  as  good  ore  as  has  Ixhmi  found  on  the  property  ; 
and  they  have  shown  this  vein  to  have  a  thickness  exceeding 
20  feet  in  many  ])lac(>s,  and  averaging  probably  10  or 
12  feet ;  while  the  middle  and  west  veins,  though  smaller, 
lifive  still  apparently  a  thickness  of  three  feet  and  uj)ward. 
On  the  Hawkeye  property,  the  west  vein  has  beenoj)ened  to  a 
width  of  about  12  feet  at  a  depth  of  about  GO  feet. 

The  gold  is  found  as  free  gold  principally  in  the  arsenical 
sulphurets,  but  it  occurs  also  in  the  cpiart/,  where  it  is  often 
plainly  visible.  The  proportion  of  sulphurets  to  quartz  in  the 
vein  has  been  ascertained  by  repeated  tests  ;  it  varies  from  10 
to  GO  per  cent  in  weight  of  the  entire  vein-stuff,  and  these 
sulphurets  carry  from  thirty  to  several  hundred  dollars  per 
ton,  while  the  entire  filling  of  the  vein,  wdthout  any  sorting 
whatever,  has  been  found,  by  careful  sampling  of  over  six  hun- 
dred tons  in  five-ton  lots,  to  run  from  $10  to  $25  gold  per  ton 
and  average  about  $20,  as  will  be  seen  in  the  annexed  record

of  sairn)ling  in  actual  milling  operations.  Selected  samples 
have  benii  found  to  carry  over  a  tliousand  dollars  to  the  ton  ; 
but  the  conclusions  arrived  at  and  stated  in  this  report  have 
been  based  solely  upon  working  I'osults,  on  large  tpiantities 
of  the  orc^  treated  just  as  it  came  from  the  mines  witbout  any 
selection  -whatever,  and  they  are  Ixdievedto  rej)resent  figures 
■\vliicli  will  be  realized  steadily  in  actual  working   operations. 

Tlie  veins  are  Ix^vond  all  doubt  true  fissures  in  syenitic 
granite — viuysimilar  to  the  famous  jniues  of  ("ornwall,  Saxony, 
and  othei'  parts  of  the  old  world,  where  th(»y  have  l)een  worked 
witli  pr(jiit  for  a  hundred  years — while  their  great  })roveu 
lengtli  and  thickness  on  this  i)ro])ertv  put  beyond  any  reason- 
able doubt  their  continued  productiveness  to  the  greatest 
depths.  * 

It  is  not,  of  course,  expected  that  the  veins  will  l)e  of  uiii- 
forrn  thickness  throughout,  or  that  the  ori's  will  l)e  iH[ually  rich 
in  ev(M'y  place  ;  on  the  contrary,  the  fissures  will  open  out  in 
some  places  and  pinch  in  others,  and  the  ore  itself  will  be  far 
richer  in  sonu^.  ])arts  of  the  vein  than  in  others  ;  but  tht^  fact 
that  Jiot  a  single  one  of  the  five-toii  sam[>les  (i'e[)resenting 
over  (300  tons)  carri-nl  less  gold  than  would  leave  a  hand- 
some profit  after  deducting  the  cost  of  mining,  milling,  and 
loss  in  treatuKvut,  justifies  the  l)elief  that  pay-ore  will  be  found 
throughout  the  entire  length  (nearly  1000  feet)  already  ju'oven 
of  the  main  chimney. 

The  or(>s,  which,  as  tdready  stated,  are  arsenical  sulphurets, 
are  in  that  condition  in  Avliich  they  occur  to  the  greatest 
depths,  and  their  richn(>ss,  with  the  usual  fiuctuations,  has  thus 
far  incr<\ised  as  depth  has  l)een  attained.  The  yield  is  more 
than  doul)le  that  of  the  Homestake,  Ulack  Hills,  Dak.,  ores 
(that  come  from  somewhat  similar  veins),  which  have  paid  such 
magnificent  returns  during  the  })ast  two  years  that  the  stock 
of  that  company  is  even  now  (August,  1880),  when  every  mining 
•  stock  is  depressed,  s<  limg  at  the  rate  of  over  13,000,000  for 
the  property.  The  quantity  of  ore  on  the  Canada  Con.  prop- 
erty being  enormous,  the  cost  of  treatment  extremely  low, 
and  its  richness  so  much  greater  than  that  of  the  Homestake

ores,  tliere  is  no  reusoii  wliy   this  property   may  not  in  tlie 
near  future  command  as  higli  a  price  as  that  famous  mine. 


III.  History  of  the  District, 

Gohl  was  first  discovered  in  this  district  in  1865  as  free 
gohl  in  tfuartz  anil  mispickel,  and  sporadic  attempts  have  since 
been  made  at  two  or  three  i)oints  to  treat  tlie  ores,  chiefly  by 
raw  arnul<famation.  As  mijjfht  have  been  anticipated  from  the 
nature  of  the  ore,  but  a  very  small  proportion  of  the  gold  was 
saved  in  this  way,  M'hile  the  expense  of  treatment  in  the  small 
and  primitive  mills  adoj^^ed  was  groat  and  the  loss  of  quick- 
silver heavy.  There  was  neither  experience  nor  technical 
knowledge  available  at  tlie  time,  and  no  sufficient  capital  to 
put  up  suitable  works  or  to  develop  the  mines,  hence  they 
have  lain  idle  all  these  years  without  a  single  serious  effort 
to  work  them  on  an  economical  basis.  Nevertheless,  many 
tests  of  the  ores  were  made,  some  on  quite  an  extensive 
scale,  in  reduction  works  in  the  United  States  and  England, 
and  the  results  were  invariably  highly  satisfactory ;  so  much 
so,  indeed,  that  the  owners  of  the  only  developed  properties, 
though  financially  unable  to  work  the  mines  themselves, 
esteemed  them  so  highly  that  they  would  not  sell  at  such  a 
price  as  Avould  offer  an  inducement  for  others  to  purchase. 
Now,  for  the  first  time,  by  consolidating  a  large  number  ol 
tracts,  and  thus  making  a  property  of  sufficient  magnitude  to 
Justify  the  establishment  of  large  works,  has  it  been  possible 
to  make  these  valuable  ores  available.

IV.  Extent  of  the  Property. 


The  property  included  in  the  present  enterprise  has  a 
length  of  about  4200  feet  from  north  to  south  on  the  strike 
of  the  several  known  veins,  and  embraces —

Total 851  acres. 

The  whole  containing  ovtT  850  acres,  some  of  which  is 
good  farming  land,  and  most  of  it  is  well  timbered.  On  near- 
ly all  of  these  lots,  gold  has  been  found  in  greater  or  less 
quantity,  though  the  veins  havf  been  opened  only  on  the  lots 
in  the  VIII.  Concession.  On  lot  27  in  the  III.  Cf)ncession, 
is  a  very  iiromising  vein  of  galena.  There  is  also  on  this  lot 
a  stream  of  Avater  with  a  fall  of  15  or  20  feet,  which  would  be 
available  in  concentrating  the  lead  ore. 

The  chief  mineral  wealth  upon  the  property  of  the  Canada 
Consolidated  Gold  Mining  Company  consists  of  the  three  or 
four  large  gold-bearing  cpiartz  veins  which  run  through  the 
lots  8,  9,  and  10,  in  the  VIII.  Concession  (jf  Marmora,  and 
which  have  been  developed  to  such  an  extent  as  to  place  their 
value  beyond  question. 

As  under  Canadian  laws  mineral  veins  can  not  be  followed 
beyond  the  limits  covered  in  the  surface  location,  care  has 
been  taken  to  secure  such  an  extent  of  property  as  will  in- 
clude the  veins  to  any  workable  depth.

V.  Amount  of  .i  )EVELorMENTS. 

The  various  shafts  and  surface  openings  as  they  existed  at 
the  date  of  their  examinations  are  described  in  detail  in  the 
accompanying  reports  of  Messrs.  R.  H.  Stretch  and  Thomas 
Couch.  Reference  is  made  to  Mr.  Stretch's  map  to  show  the 
location  of  the  veins  and  of  the  sever.al  shafts ;  it  is  not  therefore 
necessary  to  enter  into  any  further  detail  here  than  to  say 
that  the  main  shaft,  which,  at  the  date  of  Mr.  Stretch's  visit, 
•was  105  feet  in  depth,  is  now  150  feet,  and  the  ore  has  steadily

inij)rovetl,   that    now    coining  out    showing    constantly    free 
gold. 

Tlie  chief  devplopnients  consist  of  a  nuniherof  shafts  vary- 
ing ill  tli'ptli  from  a  few  feet  to  150  f(>et  (August),  situated  at 
intervals  along  the  different  veins,  asshownin  the  accompany- 
ing map,  and  ])ractic.i]ly'  ])roving  the  main  veins  for  a  length 
of  700  or  SOO  feet,  and  to  ;i,  depth  of  ]r)0  feet,  so  conclusively 
as  to  ])ut  the  (ire  technically  "  in  sight  "  ov(>r  that  extent  of 
vein  aitii.  Al)out  "200  feet  in  length  by  100  feet  in  depth  of 
tin-  niiddlt'  vein  may  also  l)e  considered  as  similarly  proven, 
while  the  continuation  of  the  veins  beyond  these  limits  and 
their  probable  j)roductiveness  are  demonstrated  by  a  great 
number  of  surface  openings  and  outcrops. 

Th(^  shafts  which  haA'e  been  sunk  have  been  on  tlu^  main 
vein  7  xy  feet  in  their  smallest  parts,  and  the  deep  shaft  has 
been  opened  out  for  a  great  part  of  itsde'pthto  a  width  acrcjss 
the  vein  of  IH  feet,  while  it  is  still  in  (juart/  on  tlu;  hanging- 
vall  side.  The  thickness  of  the  vein  at  that  point  is  there- 
fore jiruven  to  l)e  more  than  18  feet,  and  it  pro])ably  -exceeds 
20  feet  ;  while  in  the  Tuttle  shaft — the  only  other  place 
where  there  has  been  an  opportunity  to  deternune  it — the 
thickness  of  this  vein  exccM'ds  25  teet.  In  the  absence  of 
more  cross-cuts  showing  the  actual  thickness  of  the  vein  at  a 
nundier  of  points,  it  would  not  be  safe  to  assume  any  such 
thickness  as  an  average  for  the  vein  throughout ;  but  it  is 
abundantly  evident  that  the  vein  is  enormous  ;  and  as  the  de- 
velopments have  been  in  [>aY-ore  throughout,  it  is  clear  that 
the  value  of  the  proven  part  of  it,  say  700  feet  in  length  1)y 
150  feet  in  depth,  is  enormous,  amouiiting  to  about  10,000 
tons  for  every  foot  in  thickness  of  the  vein. 

Mr.  Stretch's  nnip  and  report  give  clearly  the  amount  of 
development  on  the  other  veins,  no  work  having  been  done  on 
them  since  the  date  of  his  visit.

VI.  The  Ore  in  Sight. 

The  ore  in  sight  in  any  mine  is  that  so  proven  as  to 
leave  no  doubt  as  to  its  existence  or  its  average  vabie  ;  but 
what  can  be  counted  as  so  ])roven  will  vary  in  the  different 
classes  of  mineral  d(>posits  ;  thus,  in  pockets  in  limestone, 
which  are  extremely  irregular  and  capricious,  coming  in  and 
giving  out  suddenly,  iu)t  only  would  we  reipiire  the  ore  to 
be  laid  bare  on  all  sides,  but  the  levels  and  winzes  should  be 
so  close  together  as  to  make  the  blocks  of  ore  quite  small, 
the  uncertainty  of  the  de[)osits  making  it  unsafe  to  count  as 
ore  any  large  block  of  ground  even  Avhere  its  ]>eriphery  is  all 
in  ore  ;  so  it  is  also  in  deposits  such  as  hematite  iron  ore, 
which  is  g(^nerally  a  deposition  from  springs. 

An  equal  amount  of  caution  should  be  exercised  in  esti- 
mating reserves  in  iissure-veins  where  the  ore  occurs  in  small 
chimneys  or  irregular  ]iockets,  especially  where  it  is  of  very 
high  grade  ;  for  the  grade  of  the  ore  is  as  variable  as  its 
amount,  and  th(>  variations  in  rich  ore  are  so  great  as  to 
modify  immensely  the,  value  of  the  reserves.  In  low-grade 
ore,  tlie  variations  are  necessarily  much  smalhn',  and  affect 
the  value  of  the  reserves  much  less  ;  and  if  we  have  at  the 
same  time  a  regular,  uniform  Aeiii,  Ave  can  count  Avitli  much 
greater  certainty  as  "ore  in  sight  '"  that  one  hundred  feet  on 
each  side  of  and  beloAV  actual  openings  than  avc  could  for 
fifty  or  even  tAventy  feet  on  each  side  of  openings  in  an 
irregular  vein   or  pocket  in   rich  ore. 

In, certain  classes  of  mineral  deposits — such  as  coal  beds — 
we  can  count  as  "in  sight"  or  as  "reserves"  all  the  area 
underlain  by  the  l)ed  where  proven  by  shafts  or  bore-holes  at 
intervals  of  e\'en  one  or  two  thousand  feet. 

The  veins  in  this  district  are  i)roven  by  shafts  and  surface 
openings  to  continue  over  a  length  of  several  miles,  and  the 
east  vein  is  deA^eloped  on  this  company's  property  by  shafts 
at  interA'als  of  a  feAV  hundred  feet  for  a  length  of  from  700  to 
800  feet,  and  to  a  depth  of  from  -40  to  150  feet,  and  on  the 


14 


middle  vein  by  four  shafts  to  a  length  of  several  hundred  feet, 
to  a  depth  of  about  50  feet.  Each  of  these  veins,  wherever 
opened,  has  proved  to  be  strong  and  the  ore  of  very  uniform 
quality,  as  will  be  seen  by  reference  to  the  record  of  assays 
and  mill-tests  already  made.  The  fact  that  not  only  where 
these  shafts  are  sunk,  but  all  along  on  the  surface,  the  veins 
show  immense  outcrops  of  quartz,  and,  wherever  sunk  upon 
to  a  depth  of  even  a  few  feet,  show  sulphurets,  places  it  be- 
yond any  reasonable  doubt,  that  they  carry  ore  between  the 
shafts  of  the  same  quality  and  in  the  same  quantity  as  in  the 
shafts.  Indeed,  few  estimates  of  ore  in  sight  in  blocks  driven 
comi)lptely  around  are  as  reliable  as  would  be  this  counted 
to  a  depth  of  150  feet. 

No  true  fissure-vein  in  old  rocks  having  the  immense  length 
and  width  that  this  has,  and  showing  such  remarkable  uniform- 
ity in  its  ores,  can  be  imagined  as  suddenly  giving  out  in  quanti  by 
or  yield  in  a  depth  of  a  few  hundred  feet,  and  au  estimate 
which  should  consider  as  technically  in  sight  the  ore  100  feet 
below  actual  openings  on  these  veins,  and  150  feet  on  each 
side  of  the  shafts  (the  vein  being  proven  at  small  intervals 
along  the  surface),  would  be  a  safer  estimate  of  proven  ore 
than  in  estimating  50  feet  on  each  side  of  actual  openings  in 
most  mineral  veins.  Such  an  estimate  would  generally  be 
considered  extremely  conservative. 

The  quantity  of  ore  "  in  sight" — that  is,  the  quantity  of  ore 
that  can  be  considered  as  proven  beyond  any  reasonable 
doubt  —  has  been  variously  estimated  by  the  well-known 
experts  who  have  examined  the  property,  according  to  their 
respective  ideas  of  what  constitutes  sufficient  proof  of  the  ex- 
istence of  the  ore.  Mr.  Stretch  counts  as  "  in  sight "  not  a 
single  foot  below  the  rich  ore-bearing  bottom  of  the  shaft 
{which  is  now  45  feet  below  the  point  to  which  he  counted  the 
ore,  and  is  in  richer  ore  and  the  vein  is  Avider  than  at  the  date 
of  his  examination)  or  a  single  foot  beyond  the  end  of  the 
drifts  (all  in  ore)  in  a  vein  which  he  counts  to  have  an  average 
thickness  of  12  feet  of  ore  ;  while  Mr.  Couch  considers  as 
beyond  doubt  or  "  in  sight "  in  this  vein  a  depth  from  the

■where  they  are  sunk  in  ore  and  })rove  the  vein  of  gi-eiit  thick- 
ness. Mr.  Coucli  allows  liberally  for  "horses"  and  other 
"  accidents"  in  the  vein,  and  iissumes  an  average  thickness 
throughout  of  only  five  feet.  In  this  way  he  estimates  as  "  in 
sight"  some  (51, 000  tons,  while  Mr.  Stretch  estimates  as  fully 
proven  '21,500  tons,  and  as  "probably  ol)tainable"  10,500  tons 
additional,  or  a  total  of  88,000  tons.  Both  believe  that  these 
amounts  represent  but  a  small  part  of  the  ore  which  will 
be  obtained  from  these  veins  ;  for  l)oth  are  convinced  that 
these  great  true  tissure-veins  which  have  been  proven  over 
Buch  an  enormous  length  will  continue  to  be  productive  down 
to  the  greatest  de[)tlis.  But  as  a  basis  of  jircscut  commercial 
value,  they  limit  their  estimates  of  ore  "in  sight"  as  above 
to  what,  in  their  o[)inion,  was,  at  the  date  of  their  examina- 
tions, proved  beyond  doubt  to  exist  and  t(i  be  easily  obtainable. 

The  developments  which  have  been  made  in  sinking  shafts, 
etc.,  since  these  gentlemen  examined  the  mines,  have  in- 
creased considerably  the  amount  of  ore  actually  demonstrated 
as  "in  sight,  '  and  we  believe  a  very  conservative  estimate 
would  now  })laco  it  between  50,000  and  00,000  tons,  while  the 
'"jjrubahi/ifif.s'  increase  in  full  proportion  with  the  actiially 
proven  ore. 

If  Ave  coimt  as  reserves  the  ore  in  the  main  vein,  for  a 
length  of  700  feet,  which  all  our  explorations  show  to  be  "  in 
pay,"  and  counting  only  to  the  bottom  of  the  main  shaft, 
"which  is  now  in  better  ore  than  was  found  at  any  point 
nearer  the  surface,  we  would  get  700  x  150  =-105,000  cubic 
feet,  or  say,  10,000  tons,  for  every  foot  of  thickness  of  the 
vein.  And  since  this  thickness  wherever  tested  was  from  10 
to  25  feet,  it  would  be  safe  to  count  5  feet  average  thickness, 
as  Mr.  Couch  has  done,  after  dediicting  very  liberally  for 
"  horses,"  or  poor  places,  which,  though  not  yet  met  with  in 
any  of  the  workings,  rnay  be  expected  in  this  as  in  all  other 
mines.     This  would  give  50,000  tons  in  this  vein  alone. 

The  middle  vein  would  add  several  thousand  tons  of  rich 
ore  to  this  reserve.

.  YII.  YiHLi)  OF  THE  Ore. 

The  ore  from  the  veins  on  the  Canada  Consolidated  Crold 
Mining  (^mipany's  propcn'ty  is,  as  already  stated,  gold-bear- 
ing arsenical  iron  pyrites  (mispi(dcel)  Avitli  a  quartz  and  calc- 
spar  gangne,  free  gold  being  frequently  2)lainly  visible  in 
both  the  ([uartz  and  the  mispickel.  The  veins  also  carry  in 
small  (piantity  iron  pyrites,  and  in  still  smaller  (piantity 
copi)er  sulphides.  The  ores  contain  also  silver,  but  in  such 
small  quantity  .'s  to  be  of  no  practical  value — indeed,  it 
scarcely  a]>pears  at  all  in  the  gold  produced  by  amalgamation, 
which  is  of  exceeding  purity,  some  lots  being  082  line  or  over 
23^  carats. 

The  amount  of  gold  in  the  ore,  though  variable  in  small 
samples,  owing  to  the  fact  that  some  of  it  is  coarse,  is  remark- 
ably uniform  in  large  lots  of  ore  taken  as  it  comes  from  tln^ 
mine.  There  is  no  waste  in  the  veins  except  occasional 
horses  of  country  rock,  all  the  quartz  from  the  entire  width 
of  the  lode  carrying  more  or  less  gold. 

The  gold-bearing  contents  of  the  ore  have  been  determined 
by  a  vast  number  of  assays  of  average  samples  taken  fron) 
the  various  dumps,  and  by  tests  of  large  lots  in  various  ways.

ASSAYS    OF    .\VKItA(Jr,    SAMPLES    OF   OUKS. 

Twentv  assavs,  made  at  the  (ieoloi;fical  Survey  of  Canada 
Laboratory,  of  sam])les  from  the  Marmora  mines,  <^ave  an 
av(n'a;^e  of  l-GBflT  ounces  of  j^old,  e([ual  to  S'};i81  per  ton  of 
2000  pounds.  Twelve  of  these  samples  were  from  the  Gatlin*; 
mines,  and  gave  an  average  of  10107  ounces  of  gold,  or  $39.1:7 
per  ton. 

Prof.  E.  J.  Chapman,  of  the  University  College,  Tcn'onto, 
an  abstract  of  whose  report  on  a  portion  of  this  property  will 
be  found  in  the  Appendix,  says  :  "  I  have  made  assays  of  its 
ores  from  time  to  time,  and  I  have  never  failed  to  obtain  from 
any  sample  (mispickel),  as  a  minimum  value,  at  least  fifty 
dollars  per  ton."  "  The  following;  results  wtn-e  obtained  from 
samples  collected  very  carefully,  with  a  view  to  obtain  the 
average  amount  of  precious  metal  held  by  the  undressed  ore  : 

"  No.  1,  or  East  Vein— Cbdd,  $78.50  ;  silver,  .}  oz. 

"  No.  8,  or  Middle  Vein— Gold,  .^(W.HO  ;  silver,  ^  oz. 

"O'Neil  Shaft,  middh>  vein— Gold,  $()0.2(; ;  silver,  |  oz. 

"  On  a  former  occasion,  I  obtained  from  a  small  sample 
of  the  Gatling  ore  .*112,  and  from  pure  mispickel  $150  per 
ton." 

James  Douglas,  Jr.,  whose  report  on  portions  of  this 
projierty  will  be  found  in  the  Appendix,  says  : 

"  A  sample  taken  as  fairly  as  possible  from  the  ore  piles 
on  the  Gatling  Company's  ])roperty,  the  five-acre  lot  and  the 
Hawdveye  lot,  gives  me  in  gold  1  oz.  5  dwts.,  value  $25.84,  per 
ton  of  2000  pounds."  . 

Prof.  W.  T.  Rickard,  of  London,  Avliose  report  on  this 
property  is  printed  in  the  Api)endix,  says  : 

"  I  took  samples  from  the  various  shafts  and  openings  on 
each  claim,  and  ground  them  together.  *  *  *  I  picked  out 
a  large  quantity  of  pure  mispickel,  crushed  and  sampled  and

Capt.  Benj.  Plummer,  who  examined  these  mines  for  Messrs. 
John  Taylor  it  Sons,  of  London,  carefully  sampled  the  ores 
from  the  different  openings,  and  had  his  samples  assayed  by 
Prof.  Chapman,  of  University  College,  Toronto,  who  obtainetl

18'7  tons  of  ore  from  the  se\era.l  shafts  of  the  Gatling 
Company's  mines  were  then  treated  by  the  same  parties — 
the  process  bein^'  roasting  and  amalgamating — the  roasting 
was  very  imperfect,  being  efl'ected  in  a  revolving  cylinder  only 
3  feet  diameter  and  12  feet  long,  heated  from  the  outside, 
and  -with  a  strong  draught  of  air  forced  thrtmgh  it  by  a 
"blower."  The  consotpience  was,  that  the  flue  dust  con- 
tained much  gold,  and  the  roasted  ore  carried  0  per  cent  of 
sulpluir. 

The  following  were  the  assays  of  lots  of  from  2  to  3  tons 
each  :

Average  gold  in  18-7  tons  was  $35.16  per  ton,  counting 
gold  at  $20  per  ounce. 

Gold  actually  sayed  was  $25.32  per  ton,  or  71  per  cent  of 
assay  value,  while  there  was  still  in  the  bottoms  in  flue  dust 
returnable  for  retreatment,  obtainable  gold  that  would  have 
made  the  yield  $27.31  per  ton,  or  77  per  cent,  and  the  tail- 
ings were  extremely  rich  and  could  easily  haye  yielded  on 
shaking  tables  or  belts  gold  enough  to  have  made  the  actual 
yield  $30  or  $31  per  ton.

]Jv  far  the  most  exhaustive  tests  of  these  ores  were  made 
under  my  own  direction.  Having  secured  a  working  hond 
upon  these  properties,  I  carried  on  mining  and  milling  opera- 
tions with  a  force  of  eighty  or  ninety  men  during  nearly  four 
months.  During  this  time,  seven  shafts  were  worked  upon 
and  attained  depths  of  from  forty  to  one  hundred  and  ten 
feet ;  and  two  levels  of  forty  feet  each  in  length.  Three  of 
these  shafts,  namely,  the  Tuttle,  the  A  shaft,  the  deep  shaft, 
and  two  levels  were  those  upon  which  the  most  of  the  work 
was  j)erformed,  and  it  is  to  the  ore  from  these  that  the  follow- 
ing remarks  are  confined.  These  openings  prove  a  length 
•  along  the  main  vein  of  about  seven  hundred  feet,  as  may  be 
seen  by  reference  to  the  accompanjdng  sections  from  Mr. 
.Stretch's  report.  • 

The  ore  extracted  loithoid  any  sorting  luhatever  was  taken 
to  the  mill ;  it  Avas  then  weighed  and  crushed  for  the  greater 
part  in  five-ton  lots,  every  twentieth  shovelful  as  it  came 
from  the  Blake  crusher  being  laid  aside  for  a  sample.  The 
samples  of  five-ton  lots  were  crushed  fine,  quartered  down  as 
iisualj  and  assayed  ;  thus,  one  hundred  and  eight  lota,  nearly 


TT 


22 


all  representing  Ijve  tons  of  ore,  were  assayed  separately, 
while  lifty-Dne  tons  from  the  Tuttle  shaft  were  sampled  iii 
the  same  careful  manner  in  one  lot  by  Mr.  Thomas  Macfarlane, 
of  the  Wvandotte  Silver  Smelting  Company.  The  assavs 
of  these  several  samples  are  given  in  the  following  table. 
It  will  be  noted  that  tlie  richer  live-ton  lots  were  obtained 
by  selecting  the  heavier  sulpluirets  from  the  balance  of 
the  ore  in  the  ore-honse  so  as  to  demonstrate  the  ellect  of 
rouj-li  hand-sortincr ;  the  low  assays  were  therefore  of  second- 
class  ore  ;  the  whole  nund)er  of  assays  gives,  hoAvever,  the 
average  yield  of  the  ore  just  as  it  conies  from  the  mine  with- 
out sorting.  The  higher  assay  numbers  (last  assays  made) 
were,  in  general,  from  ore  mined  nearest  the  surface,  and 
which  <:ccordingly  was  found  at  the  center  of  the  dump. 
Nearly  oVie  half  the  dump  was  milled,  and  the  last  milled  came 
from  the  center  of  the  dumj). 


Note.-  The  proportions  of  ftold  and  silver  in  the  assay  buttons  were  obtained  by  partinf,' 
89  buttons  in  (ine  operation.  .  wa.s  found  the  average  was  6^  per  cent  gold,  8i  silver.  The 
following  tiible  give.s  only  the  gold,  or  08  per  cent  of  the  weight  of  the  button  :

The  ore  from  tlie  Tutth^  shaft  avus  found  to  be  much 
richer  than  that  from  the  same  v(*iu  <in  the  (ratling  property. 
The  average  of  63  tons  sampled  by  Thomas  Macfarlane  and 
Kothwell,  and  assayed  by  Gifford  and  Thies,  was  $24.88. 

And  assuming,  as  would  be  fair,  that  seven  tenths  of  the 
reserves  in  the  main  vein  are  of  Gatling  ore,  and  three  tenths 
of  Tuttle  ore,  we  would  get,  as  the  average  value  of  the  main 
vein  ore,  $17.30  per  ton. 

The  ore  from  the  middle  vein  has  been  found  richer  than 
that  from  tlie  main  vein.  Lots  aggregating  12  tons  were 
sampled  under  my  direction,  and  averaged  i;30.82  per  ton 
— a  figure  lower  than  that  given  for  larger  lots  shipped  to 
Swansea,  to  New  Hampshire,  and  elsewhere.  Assuming  the 
same  yield  for  th»i  ore   from  the   O'Neil    shaft,  and   allowing 

^  only  one  tenth  of  the  reserves  of  ore  to  be  in  the  middle  vein 
and  O'Neil  shaft,  and  nine  tenths  of   the  reserves  to  be  in  the

From  the  above  table,  giving  the  average  results  of  the 
careful  sampling  of  these  mines  by  well-known  and  reliable 
experts,  we  note  the  remarkable  uniformity  of  the  results 
arrived  at,  and  the  unanimity  of  the  opinion  that  large  profits 
can  be  made  by  the  treatment  of  these  ores.  The  lowest 
value  found  in  sampling  Avas  by  Mr.  Stretch,  and  his  figure 
results  from  the  fact  that  at  that  particular  time  the  drifts 
happened  to  be  in  low-grade  ore,  and  only  one  fifth  of  his 
samples  was  taken  from  the  Tuttle  shaft,  while  no  sample  at 
all  was  taken  from  the  middle  vein,  which  all  our  assays  sho^v 
runs  fully  $30  per  ton.  Moreover,  Mr.  Stretch's  samples  were 
but  one  ton  each,  and  therefore  do  not  give  as  reliable  an 
average  value  as  the  elaborate  series  of  tests,  on  about  600 
tons,  made  ur  ier  my  direction.  In  fact,  I  have  no  knowledge 
of  a  single   instance    where   a   mine   was   as   carefully   ami

($18.(55  gross  or  $11.50  net  per  ton)  I  believe  are  such  as  can 
be  obtained  or  surjjassed  in  regular  working  operations. 
^S  P^g^s,  "vvo  "With  this  conviction,  I  have  myself  invested  in  this  property,

The  net  vahie  of  the  ore  in  sight  is  obtained  in  my  own

with   supplies    of   all  kinds   remarkably   cheap.     There   ,q^ 
excellent  macadamized   roads  and  the   railroad  within  u: 
miles  of   the  mines  ;   and  there  will  soon  be  a  telegraph  li

3.  Water,  which  is  as  essential  to  the  success  of  a  miu: 
enterprise  as  is  rich  ore,  is  here  so  abundant  that  a  fall^^j 
over  30  feet  on  the  Moira  River  will  furnish,  for  nine  or  i^q^

OPINIONS    OF    EXPERTS   AS    TO    THE   VALUE    OF

Mining  Engineer,   October,  187o. 

Eeferring  to  the  (latling  Company's  lot,  Professor  Cliapman 
says  :  This  portion  of  the  Company's  property  has  been 
known  to  me  for  some  years,  and  I  have  already  expressed 
a  high  o])inion  of  its  value.  *  "^'  ••'  I  have  made  as.-iays  of  its 
ores  from  time  to  time,  and  I  have  never  failed  to  ol)tain  from 
any  sample,  as  a  minimum  value,  at  least  fifty  dollars  per  ton. 
*  *  "  There  can  be  no  doubt,  theref(ire,  as  to  the  fact  that 
an  enovnlous  amount  of  gold  must  be  locked  up  within  the 
limits  of  the  pro]>erty.     -      "     * 

This  part  of  Marmora  is  occupied  by  a  series  of  gneissoid, 
syenitic,  and  other  crystalline  strata,  *  *  They  are  inter- 
stratilied  in  several  places  with  remarkable  bands  or  lodes  of 
auriferous  mispickel,  associated  principally  with  quartz,  but 
containing  also  in  places  small  quantities  of  cubical  pyrites, 
mica,  calcite,  magnetic  iron-oxide,  and  other  sul)stances.  In 
addition  to  small  strings  and  so-called  feeders  of  ore,  four 
distinct  bands  of  workable  dimensions  have  been  traced  en- 
tirely across  the  location  from  north  to  south.  *  *  *  The 
bands  have  all  the  characters  of  regular  veins.  *  *  *  The 
east  lode,  *  *  *  at  a  depth  of  about  60  feet  from  the  sur- 
face, exhibited  an  evidently  increasing  width  of  16  feet. 
It  consists   essentially    of   a  quartz    gangue,  carrying   large

Tin)  tlrst  or  east  vein  is  about  150  feet  westward  of  the 
river  Moira,  and  the  fourth  al)out  ::{5()  feet  still  farther  to 
the  Avestward;  the  intervening  second  and  third  veins  being 
nearly  equidistant,  thereby  offering  great  facilities  for  cross- 
cutting  in  de])tli,  and  working  from  the  same  shaft  if  con- 
sidered desirable. 

Tl'./^  width  of  the  veins  is  variable  ;  the  minimum  may  be 
put  down  at  three  feet,  and  the  maximum  at  eighteen  feet. 
For  instance,  the  large  shaft  on  the  east  vein  shows  an 
average  width  of  twelve  feet;  No.  8  vein,  in  the  20-foot  shaft 
(where  it  shows  much  visil)le  gold),  five  feet  :  and  on  No.  4 
vein,  a  width  of  live  feet  is  also  found.     -^     '•'     *     *     * 

In  order  to  arrive  at  a  practical  estimate  of  the  ores 
exposed  by  shafts  sunk,  and  by  outcrops  of  the  three 
prini'i])al  veins,  1  vrould  calculate,  for  each  vein,  an  average 
width  of  only  four  feet  across  the  prq|)erty,  wliic-h  might  ccm- 
fidently  be  relied  upon  as  a  Avorking  aver!ig(\  and  an  average 
of  fifty-live  feet  in  depth  on  eai'li  vein.  We  tJius  have  in  sight 
on  each  of  the  three  veins  111,100  cubic  feet  of  ore,  or  for  the 
three  veins  333,H00  cubic  feet,  which,  reckoned  at  eight  cubic 
feet  per  ton  m  situ,  gives  41,002^  tons.

Opinion    of  John    ('.    F.   B'linlo/ph,  Jfininr/      EtKjincci',     In  a 

I'll  or  dated  Octoher,  1878. 

I  visited  the  CJatliiig  mining  property  a  few  years  since. 
I  was  extr<^niely  pleas(Hl  with  it.  It  carries  three  strong,  wide 
veins  well  marked,  cutting  through  the  metaniorphic  rocks. 
The  ore  consists  of  quartz  carrying  free  gold  and  containing 
large  amounts  of  mispickel  carrying  gold.  The  ore  is  not  an 
easy  one  to  handle,  but  it  contains  a  good  deal  of  gold.  It  is 
an  extremely  Avaluable  property.

Opbtinii  of  Adolpli    Tides,  Mining  Engineer  and  Metcdlurgist, 

June,  1880. 

Mr.  Thies  acted  as  Assayer  and  General  Manager  of  the 
mines  and  mills  during  the  time  they  were  heing  Avorked  by 
R.  P.  Eothwell,  under  an  option  of  purchase  ;  he  therefore 
had  the  very  l)est  opportunity  for  becoming  familiar  with  all  the 
facts  in  the  case,  and  his  long  and  varied  practical  experience 
in  many  parts  of  the  world  entitles  his  opinion  to  great  weight. 

He  says  :  I  have  always  considered  the  Gatling  and  Tuttle 
property  a  very  valuable  one.  Having  had  the  opportunity 
of  examining  the  underground  workings,  and  of  making  the 
assays  of  the  ores  and  of  noting  the  method  of  concentration, 
amalgamation,  etc.,  I  could  from  my  past  experience  in  gold 
mining  make  a  comparison  of  value. 

From  the  dpveloi)ments  made  on  the  several  parallel  veins 
on  the  property,  no  one  can  doul)t  their  persistence  downward. 
Contractions  of  the  veins  occur,  but  no  pinching  out.  The 
thickness  of  the  veins  is  so  great  there  can  be  no  lack  of  ore 
— the  first  essential  in  a  mine — and  of  such  richness  as  to  leave 
a  very  handsome  margin  of  jirofit.  My  assays  on  515  tons  of 
crndp  unsorted  ore  gave  mc  an  average  of  $13.37  in  gold  per 
ton,  and  this  will  certainly  pay  well  in  a  country  where  labor 
and  su])]dies  are  as  chea])  as  in  Canada. 

With  the  mine  opened  for  stoping,  the  cost  of  mining 
should  not  exceed  $2  per  ton,  and  for  concentration,  roasting, 
and  amalgamation  or  chlorination,  should  not  be  more  than 
from  $1.50  to  !ii!2  per  ton,  so  that  H  per  ton  at  the  outside 
will  coA-er  all  the  cost  of  Uiuiing  and  treating  this  ore.  The 
successful  roasting  of  these  ores  in  the  revolving  cylinder  has 
greatly  lessened  this  item  of  expense,  and  the  facility  Avith 
which  the  roasted  ore  amalgamates  has  been  fully  shoAvn  in 
my  Avork,  Avhere  I  obtaineil  80  per  cent  of  the  assay  value. 
The  thorough  concentration  of  tlie  ore  by  jigs  and  belts  pre- 
sents no  difficulty,  and  it  is  in  my  opinion  a  very  important 
consideration.  So  far  as  my  personal  knoAvledge  of  these

Abstract  of  Report  of  Captain   Thomas  Couch,  Jihdng  Expert, 

Fehruarij,  1880. 

*  *  ^  "■'■  Throughout  almost  the  entire  length  of 
these  combined  properties  are  traceable  three  strong,  persis- 
tent lodes,  coursing  nearly  north  and  south  through  syenitic 
granite.  ^'  ^  ^-  The  bulk  of  matter  Avith  wliich  these  lodes 
are  filled  is  quartz  interspersed  with  auriferous  mispickel, 
copper  pyrite  (tiie  latter  rarely),  and  occasionally  horses  ;)f 
country  rock,  which  are  found  heie  as  in  all  true  lodes.  ■■•  " 
These  lodes,  like  others  of  their  character,  will  be  found  to 
expand  and  contract  alternately,  both  in  their  trend  and 
depth-  "■  "■  ""  "  The  thickness  of  the  lodes  is  A'ariable. 
The  west  lode  is  three  to  four  feet ;  the  middle  lode  is  three  to 
four  feet.  The  main  lode  is  four  to  twelve  feet  wide.  ''^  ■'  ••'  ■■' 
All  the  foregoing  facts  together  give  evidence  of  strength  and 
persistence  of  continuity  in  length  along  the  respective  lodes, 
and  must  be  regarded  as  proof  of  continuity  to  the  deep  ;  for 
no  better  or  stronger  evidence  of  tht.  fact  could  be  adduced 
except  actual  developments. 

The  gold  in  the  lodes  of  tln^  combined  property  is  found 
pariilj  free  in  quartz,  au''  p.  Jy  associated  with  mis})ickel. 
The  former  is  easily  ext^a-cted  from  the  rock,  after  pulver- 
izing, by  panning.  This  part  of  the  gold  is  found  pi.  cipally 
near  the  surface,  at  poii,..-,  ,vhere  the  sulphureted  i  iv  have 
been  decomposed  by  at  a  osi)]ieric  agencies.  But  it  is  by  no 
moans  confinet.l  to  this ;  fcr  a  day  scarcely  passes  tl.at  gold  is 
not  seen  by  the  unaided  oye  in  the  ore  from  all  points  where 
work  is  being  prosecuted.  Bf^sides,  by  pulverizing  the  purest 
of  the  mispickel,  it  can  be  panned  out  in  variable  rpiantities. 
The  value  of  the  property,  however,  depends  in.  inly  upon 
the  yield  of  the  arsenical  pyrites,  .vhicD  *.ip  knovvii  to  contain 
the  greater  portiini  of  the  gohi. 


tmm 


38 


This  fact  is  one  of  great  impovtanoe,  as  it  proves  beyond 
peradveuture  that  the  lodes  do  not  depreciate  in  value  below 
tho  water-line,  and  can  be  depended  npon  to  yield  to  a  great 
depth.  It  must  be  )-emeinl)ered  that  the  sulphureted  ores 
are  not  evenly  distributed  throughout  the  entire  lode,  but 
will,  as  is  the  case  in  all  iodes,  be  found  in  spots  and 
chimneys,  alternating  with  comparatively  barren  zones. 

My  samples  consisted  of  lots  from  1000  to  4000  lbs., 
taken  ])romiscuously  from  the  several  points  now  being 
o])erated,  as  it  is  hoisted  from  the  shafts  and  levels.  These 
ores  were  first  run  tlirough  a  Blake  crusher,  and  as  each  lot 
was  shovehnl  to  the  mill  battery  every  tenth  sliovclful  was 
thrown  aside  for  a  sample.  The  results,  as  obtained  from

Company's  505  feet  and  195  feet  of  the  Tuttle  claim,  making 
the  length  700  feet.  In  de])th  I  have  gone  something  more 
than  50  feet  below  the  lowest  ])oint  of  exploration,  making  a 
depth  of  150  feet.  |Tlie  shaft  is  now  down  150  feet,  or 
to  the  limit  included  in  Captain  Couch's  estimates,  and 
the  higli-grade  ore  now  produced  shows  how  correct  was  his 
opinion. — R.  P.  R.]  The  average  thickness  of  this  lode,  as 
exposed  along  its  line,  is  fully  7  feet ;  but  to  allow  for  waste,

figure.  "We  liave  therefore  52,500  tons,  aUowing  10  cubic 
feet  for  one  ton. 

Middle  Lode. — The  thickness  of  this,  in  the  ojieniugs  made 
upon  it,  is  about  4  feet ;  allowing  for  contingencies  as  above, 
I  shall  calculate  it  at  3  feet ;  length,  '200  feet,  or  about  50  feet 
on  each  side  of  the  two  shafts  ;  and  at  a  depth  of  100  feet, 
about  50  fee't  deeper  than  the  explorations.  "We  have  then 
6000  tons. 

The  West  Lode. — O'Neil  shaft:  1  have  in  my  calculation 
allowed  50  feet  on  each  side  of  the  sh;ift  and  100  feet  deep

While  it  can  hardly  l)e  considered  justice  to  the  property  to 
entirely  ignore  the  unexplored  lode  (office  vein),  whose  out- 
crop is  traceable  for  such  a  length  along  the  surface,  and  yield- 
ing gold  at  every  point  that  has,  thus  far,  been  tested  by 
panning,  I  do  not  feel  warranted  in  making  a  definite  estimate 
upon  it,  or  any  lode  that  is  not  explored  at  some  point  below 
the  surface  outcrop.  I  do  not  hesitate  to  say,  however,  that  I 
am  of  the  firm  opinion  that  this  lode  will  be  found  to  be  a 
source  of  ])rofit  to  its  owners.  Also,  while  the  above  quantity 
of  ore  may  safely  be  considered  as  now  technically  in  sight, 
this  ':-  \>ut  a  small  part  of  the  ore  which  I  believe  will  be 
deAeij^toi'  in  sinking  the  shafts  and  driving  levels  as  recom- 
ir-'     •}'n\. 

IIi''"i'fi/e. — At  the  time  of  my  examination,  the  shafts  on  this 
proptioy  v>-G.;e  nearly  full  of  water,  wliicli,  together  with  the 
snow  covering  the  surface,  rendered  it  impossible  to  make  a 
complete  and  satisfactory  examination.  I  am  informed  by 
reliable  persons  tliat  the  three  shafts  sunk  on  this  property 
are  respectively  50,  25,  and  25  feet  deep,  and  that  the  lode  is 
7  to  15  feet  thick. 

Judging  from  the  quantity  of  ore  lying  around  these  re~ 
.!;pee'-^''"j  shafts,  the  inclination  and  course  of  the  vein,  and  the 
ainolar'l/j  of  the  ore,  as  compared  with  that  of  the  other  mines^ 


40 


together  with  the  great  power  of  the  veins  on  the  latter,  which 
course  directly  toward  this,  I  believe  these  openings  to  b© 
on  the  extension  of  the  two  lodes  opened  south  of  them. 
Every  thing  in  its  surroundings  leads  to  this  conclusion,  and 
proves  besides  the  persistence  of  the  lodes. 

There  is  a  20-stamp  mill  upon  the  property  equipped  with 
every  thing  necessary  for  the  reduction  of  the  ores.  ^  * 
*  *  #  •?:-  ^Yiiiie  I  do  not  think  that  it  will  be  found  diffi- 
cult to  treat  these  ores  satisfactorily,  and  Avithout  much  ex- 
perimental expense,  I  can  not  insist  too  strongly  on  the 
necessity  of  having  the  ores  reduced  under  the  supervision  of 
the  most  practical  anc  killful  manager  that  can  be  found. 
Upon  this  the  success  u.  uh  of  every  other  enterprise, 

largely  depends.         ^-         ••         ■• 

The  natural  facilities  afforded  by  this  district  for  mining 
are  not  equaled  by  any  other  I  am  familiar  with.  It  is 
situated  in  the  heart  of  a  timbered  country,  and  traversed  by 
a  river  that  furnishes  sufficient  water  to  operate  200  or  more 
stamps  at  least  eight  months  in  a  year.  *  *  "  * 
Labor  is  obtained  at  from  $1  to  $1.25  per  day,  cord-wood 
for  $1  to  $1.25  j)er  cord,  and  other  material  correspondingly 
cheap.         *         *         ^^         - 

In  consequence  of  the  vein-stone  being  hard,  development 
by  sinking  shafts  and  driving  levels  Avill  be  necessarily  slow. 
To  facilitate  this  part  of  the  development,  I  would  recommend 
the  introduction  of  rock-drills  ;  by  the  use  of  these  machines, 
I  think  the  progress  of  nearly  a  foot  a  day  can  be  made  in 
sinking  a  shaft  10  x  5  feet.  All  of  this  work  should  be  done 
by  contract ;  by  adopting  this  method,  and  furnishing  the 
contractors  Avith  drilling-machines,  I  think  the  cost,  includ- 
ing all  necessary  material,  will  not  exceed  |12  to|15  per  foot. 
A  shaft  of  these  dimensions  will  yield  from  the  main  lode  5- 
tons  of  ore  per  foot.         *         *         -x-         * 

The  cost  of  mining  in  exploration  [given  in  detail]  is 
something  over  $4  per  ton.  This,  it  must  be  borne  in  mind,  is 
in  the  actual  development  in  opening  reserves,  without- 
counting  in  any  stoping.     As  soon  as  the  mine  is  opened  to- 


41 

a  sufficient  extent  to  julmit  of  stoping  from  the  roof  of  the 
levels  upward,  the  cost  to  produce  one  ton  of  ore  will  not 
exceed  $1.25.  The  average  cost  of  mining,  including  dead- 
work,  will  not  exceed  $2.20  per  ton.   *   *   ■•    * 

The  cost  of  milling,  roasting,  amalgamating  and   hauling, 
[given  in  full  detail]  amounts  to  $1.80  per  ton.  ~ 

^  Profits.— The  average  assay  value  of  the  ore  from  the  main 
vein  is  $21.39  per  ton.  in  my  ealculaticm  upon  the  reduction 
of  the  ore,  20  per  cent  of  the  assay  value  is  allowed  as  loss 
in  the  operation.  Hence,  we  have  as  the  net  value  of  one  ton 
from  the  main  vein  $17.11,  less  the  average  cos-!,  of  mining  and 
milling,  $8.50  per  ton,  leaving  net  value  $13.61   per  ton,  on 

62,500  tons,  equal  to $714  500 

Middle  vein,  average  assay  value  of  ore  $32.05  per 
ton,  less  20  per  cent  loss— $26.12,  less  cost  min- 
ing and  milling,  $3.50  per  ton,  gives  net  value  of

O'Mil  shaft— iiOOO  tons  in  sight,  same  vet  value  after 

deducting  mining,  milling,  and  loss 67,900 

Total  net  value  of  ore  in  sight $918,000 

*  *  *  It  is  Avell  known  that  ore  in  veins  is  found  in  chutes , 
chimneys,  and  blotches,  alternating  with  poor  zones  of  similar 
shape.  *  *  *  Again,  the  chimneys  of  ore  are  never  found 
to  be  of  the  same  uniform  grade,  and  where  a  lode  is  de- 
veloped by  shafts  only,  without  having  extended  longitudinal 
galleries  to  prove  the  extent  of  the  rich  or  barren  chute,  the 
surroundings  must  be  carefully  considered  and  the  investigator 
can  hardly  be  too  conservative  in  estimating  the  value  of  a 
mining  property. 

The  Marmora  gold  mines  are  no  exception  to  the  thou- 
sands of  mines  I  have  already  seen.  I  have  proven  to  my 
satisfaction  that  there  are  rich  and  poor  chutes  in  those  lodes 
as  in  all  others.  Two  shafts  on  the  so-called  west  lode  are 
ir  chutes  of  different  quality  of  ore.  The  south  shafts  on  the 
•middle  lode  are  in  good  ore.     The  north  shafts  on  the  Hawk- 


42 


eye,  nearly  1200  feet  clistant,  wliicli  I  believe  -to  be  on  the 
same  lode,  are  in  a  chute  of  low-grade  ore,  while  the  three 
shafts  on  the  east  lode  are  all  in  good  ore,  with  variations, 
whii'li  proves  a  chute  of  great  extent.  Knowing  these  changes 
in  the  constitution  of  lodes  are  inevitable,  I  have  made  liberal 
deductions  for  them  in  this  as  in  all  other  properties ;  but, 
taking  into  consideration  all  things  relating  to  these  lodes, 
their  persistence  in  length,  their  width,  their  geological  rela- 
tion to  the  old  schists  and  granites,  and  the  true  vein  quartz 
gangxie,  coupled  with  ore  in  paying  (p;antities,  besides  l)eing 
surrounded  with  every  facility  for  cheap  mining  ;  accessible  at 
all  seasons  of  the  year,  in  a  healthy  climate,  I  can  not  but 
say  that  I  believe  the  lodes  are  of  the  most  permanent 
character,  and  will,  by  the  exercise  of  due  care  in  the 
reduction  of  the  ore.'j,  '  o  a  source  of  continuous  profit  to  their

Abstract  of  Ilcport  hi/  B.  II.  Stretch,  Mining  Engineer,  dated 

ApriJ,  1880. 

*  ^  *  The  facilities  for  conducting  mining  operations 
very  economically  are  seldom  surpassed.  Labor  is  fairly 
abundant  at  rates  r;uigiug  from  Jjjfl  to  $1.50  per  diem,  the 
latter  only  for  skilled  ;  the  average  for  a  large  gang  of  men 
need  not  exceed  $1.25.  *  •■  "^  *  A  two-horse  team  with 
driver  commands  about  $2.25  per  diem.  Good  board  costs 
§2.50  per  Aveek.  -  "'  "  Firewood  is  worth  $1  to  $1.25 
a  cord.  Pine  Lumber  at  the  mills,  about  4  miles  from  the 
mines,  is  worth  $8  per  M  ;  in  quantity  it  can  be  contracted 
for  at  $8.50  delivered.  Timber. — Mining  timbers,  partly 
squared,  are  said  to  be  worth  about  3  to  5  cents  per  running 
foot,  in  sizes  ranging  from  8  to  12  inches.  The  country  is 
heavily  timbered,  so  that  there  need  not  be  any  fear  of  serious 
changes  in  these  prices  for  many  years  to  come. 

Supplies. — Shoes   and  dies,  and  similar  iron  castings,  are 
•worth  at  present  about  4  cents  per  pound.     Salt  not  over  $1Q» 


43 


per  ton,  or  half  a  cent  per  pound.  Limestone  is  only  nominal, 
as  it  is  everywhere  abundant,  and  sulphuric  acid,  manufac- 
tured at  Broekville,  Ont.,  is  worth  2^  cents  per  pound  in 
Belleville,  in  comparatively  small  (piautities. 

Wafey. — Water  is  alnmdant  everywhere.  The  Moira  Kiver, 
which  is  now  fully  70  feet  wide,  runs  parallel  with  the  vcmuh  a 
few  hundred  feet  to  eastward  of  them  and  within  a  thousand 
feet  of  the  princi]:)al  openiny;s,  has  a  succession  of  small 
rapids  and  one  fall  of  25  or  30  feet.  -•  -  *  ]3y  a  low  dam 
and  a  short  shallow  earth-cut,  a  first-class  mill  site  can  be 
made  just  east  of  the  Mormon  shaft,  which  would  secure  a 
fall  of  fully  30  feet,  and  have  an  aT)undant  power  for  all 
necessary  machinery  during  at  least  eight  months  out  of  the 
year.  During  the  balance,  it  is  probable  that  it  would  have 
to  be  supplemented  by  steam  power.  ■'"  -  *  (liuference 
to  Map.) 

Five  gold-hearing  veins  are  more  or  less  distinctly  proven  by 
outcrops  and  exploration  to  exist  on  the  pr(,perty.  They  run 
north  and  south  near  its  eastern  boundary  and  dip  to  the  west, 
in  which  direction  the  i^roperty  extends  so  far  that  there  is  no 
danger  of  their  running  beyond  its  boundary  in  any  possible 
exploitable  depth.  ^'  ■•  ■■•  -  *  AYhile  the  belt  can  be 
pretty  thoroughly  traced  for  over  3000  feet  through  the 
property,  that  portion  which  is  best  known  lies  on  the 
Gatling  Co.'s  and  Tuttle  groiinds,  and  covers  an  area  of  about 
800  feet  north  and  south  by  300  feet  east  and  west. 

East  or  Main  Vein. — This  Ai^in  first  shows  itself  distinctly 
near  the  south  lines  of  the  Tuttle  property,  as  a  strong  iron- 
stained  quartz  outcrop  (square  E).  Two  hundred  feet  to  the 
north,  the  same  quartz  again  comes  to  the  surface,  and,  as  usual, 
discolors  the  ground  red  (s(piare  E  3);  one  hundred  and  eighty 
feet  to  the  north  (square  T  4)  the  outcrop  is  exceedingly  strong ; 
but  the  quartz,  though  iron-stained  in  tlie  joints,  seems  to  be 
barren  in  the  old  shaft  on  the  east  side  of  the  road.  The  vein  at 
this  point  is  so  flat  (about  15  to  20^)  that  to  avoid  destroy- 
ing the  road,  a  new  shaft,  called  the  Mormon,  was  sunk  to  the 
'west.    This  is  now  fifteen  feet  deep,  has  drained  the  accumulated 


44 


surface  water  from  the  old  shaft,  and  appears  to  have  entered 
the  hauj^nn^,'-\vall  of  the  vein.  The  rock  is  stained  pale  red,  and 
is  a  mixture  of  syenite,  mica,  qilartz,  cale-spar,  and  mispickel, 
but  is  not  yet  thoroujj;hly  mineralized.  The  vein  is  probably 
ten  feet  thick,  and  its  structure  will  ba  easily  understood  by 
the  cross-section  on  the  map. 

Two  hundred  and  fifty  feet  to  the  north  (sq.  E  F  7)  a  small 
pit  (D)  was  sunk  to  the  west  of  the  road  in  which  the  quartz 
(iron-stained)  Avas  found  to  lie  very  fiat,  and  in  small  quantity. 
West  of  these  two  last-mentioned  developments  (sq.  E  (5),  a 
fallen  tree  shows  considerable  quart/  among  the  upturned 
roots.

Fourteen  liundred  and  fifty  feet  north  of  the  first  outcrop 
mentioned,  and  near  the  north  line  of  the  Tuttle  property 
(sq.  D.  15 ),  we  come  to  the  Tuttle  shaft,  which  ''"  "  * 
is  now  88  feet  deep.  -  ••-  "  ••  The  first  30  feet 
was  sunk  vertically,  about  9  feet  square,  all  in  ore.  At  this 
dei)th,  the  probable  foot-wall  was  struck  with  a  westerly  dip 
of  about  GO".  A  little  work  was  done  in  this  foot-wall  to  deter- 
mine the  fact,  and  the  rock  therefrom  is  the  only  waste  on  the 
dump.  The  shaft  was  then  changed  to  the  dip  of  the  vein, 
and  the  bottom  is  still  in  ore  with  no  sign  of  a  hanging-wall. 
These  facts,  as  will  be  seen  by  reference  to  the  cross-section 
of  the  shaft  on  the  map,  make  the  probable  width  of  the  vein 
at  this  point  about  25  feet.  Water  was  struck  in  the  bottom 
of  the  shaft,  Avhich  proved  to  .be  connected  with  that  in  the 
"A"  shaft,  and  also  with  a  spring  about  GO  feet  south  of  the 
shaft.         4<-         *         *         x-         j^   ijr^s^   jjQ^v   risen  to  within 

about  5  feet  of  the  top  (being  about  7  feet  above  the  Avater  in 
the  river)  and  stands  at  a  corresponding  level  in  the  "  A " 
shaft.  This  shaft  has  produced  about  251  tons  of  ore,  or  about 
6.2  tons  to  each  running  foot.  *  *  *  *  ^j 
sample  of  one  ton  from  the  bottom  of  the  shaft,  carefully 
crushed  and  sampled,  gave  me  l)y  assay  |19  per  ton  of  2000 
pounds. 

One  hundred  and  twenty-five  feet  north  of  the  Tuttle  shaft* 


45 


* 


we  come  to  the  "  A  "  shaft  (sq.  1)  17).  This  *  *  -  is 
now  46  feet  deep.  *  "  ^^  The  shaft  Jias  jiroduced 
about  119  tons  of  ore.  ^-  -  *  TJie  shaft  has  a  waste 
dump  of  about  00  tons  or  over.  '^'  ■-"  "■•  My  sample 
from  one  ton  from  the  bottom,  carefully  crushed  and  samph)d, 
gave  me  a  result  of  :*18.25  per  ton. 

For  80  feet  west  of  the  shaft,  numerous  outcrops  of  (pinrtz 
can  be  seen  which  approach  each  other  rapidly  on  the  south 
and  sesm  to  concentrate  at  or  just  north  of  the  Tuttle  shaft. 
The  continuity  of  the  east  branch  of  the  vein  from  the  "  A  " 
to  Tuttle  shaft  is  i)roved  by  Hve  small  cuts  (see  Map,  tier  1(5) 
showing  kindly  iron-stained  porous  quartz,  and  the  western 
branch  is  well  shown  in  the  outcrops  (untouched).  No  cut 
has  been  run  across  these  stringers  to  determine  tlu^ir  value. 

Two  hundred  and  ninety-seven  feet  north  of  the  "A" 
shaft,  we  come  to  the  (h^ep  shaft.  The  intervening  ground  has 
not  been  provc^d  by  surface  ex])loration  ''^  "'  ■'■  except 
just  south  of  the  fence  (1)  17),  and  I  had  the  outcrop  again 
exposed  in  mineral  in  the  garden  (D  18),  about  midway 
betAveen  the  sliafts  at  a  depth  of  two  fei't.  It  here  showed 
stringers  of  good  mineral;  but  I  did  not  expose  the  main  vein, 
as  the  surface  (L'bris  over  it  is  fully  10  feet  thick. 

The  deep  shaft  is  tha  most  important  development  on  the 
property.  '"^  "'  "'•"  It  was  sunk  a  little  over  70  feet  some 
years  ago,  and  has  been  continued  this  winter  to  a  depth  of 
105  feet.  The  ex])lorations  at  the  70-foot  level  extend  from 
the  center  of  the  shaft  46  feet  to  the  north  and  41  feet  to  the 
south.  Near  the  surface,  the  vein  Avas  somewhat  mixed,  but 
rapidly  opened  in  ore,  until  the  top  and  bottom  of  the  incline 
are  18  feet  apart  in  the  Avidest  place,  Avith  quartz  yet  on  the 
upper  side.  The  shaft  Avas  then  contracted  (for  economy  in 
sinking)  to  a  higlit  of  ten  feet  at  the  level  of  the  drifts,  and  again 
to  seven  feet  beloAv  the  same.  At  the  bottom,  105  feet  doAvn, 
the  apparent  foot-Avall  has  flattened  and  reduced  the  thick- 
ness of  the  ore-seam,  Avhich  is  noAv  nearly  pure  mispickel,  to  less 
than  tAvo  feet  in  thickness.  It  has  been  smaller,  but  shoAvs  signs

tree  50  feet  west  (sq.  D  21^1  be  the  same  thing,  which  is  more 
than  probable.  The  outcrop  at  this  point  is  strcnig,  but  does 
not  seem  to  b^  mineralized. 

Two  hundred  and  sixt}-  feet  nortli,  with  faint  intermediate 
indications  becoming  stronger  northerly,  we  come  to  the  South 
Hawkeve  Shaft  (D  2G),  Avhich  is  about  25  feet  deep  and  dips 
strongly  to  the  west,  with  a  heavy  body  of  quartz.  The  dumps 
are  large,  and  I  judge  that  nothing  has  been  hauled  away.  In 
the  bottom  of  the  shaft,  the  foot-wall  iiattened  and  cut  out  all 
the  quartz  except  al)out  two  feet,  Avhich  seems  to  be  again 
increasing  in  size  and  carries  ([uartz,  calc-spar,  red  hematite 
iron,*  iron  ])yrites,  and  but  little  arsenical  pyrites  or  mis- 
pickel.  With  the  exception  of  a  few  small  pits,  the  reddish 
discoloration  of  the  earth,  and  some  little  quartz  at  the  inter- 
section of  the  road  (C  29),  nothing  is  seen  of  the  vein  until  it 
again  crops  very  boldly  in  the  Ioav  land  580  feet  north  of  the

still  farther  north  and  near  the  lim;  of  fault,  which  seems  to

but  it  must  have  had  a  fair  strength,  judging  from  the  size  of

found  many  fragmt'iits  of  on?  showing  free  gold  both  in  the 
solid  pyritps  and  ch'an  cpiartz.  This  result  is  confirmed  by 
the  trial  of  fiv(?-tou  lots  taken  from  the  dumps  which  l)y  care- 
ful sampling  gave  a  result  of  !ii!l4.70  and  $39.20  per  ton.  *  * 
*  *  There  must  be  still  left  on  the  dumps  of  thes(s  two 
shafts  fully  55  tons,  which,  Avith  the  24  tons  above  spoken  of, 
Avonld  give  a  total  of  about  79  tons.  This  for  48  feet  of  shaft 
(which  Avas  probably  a  greater  dej)th  than  Avas  really  obtained, 
as  I  Hnd  ail  the  old  depths  overt'stimated)  Avt)uld  be  nearly 
three  tons  per  foot  of  shaft,  and  indicate  a  Avidth  of  about  3 
feet  for  the  vein. 

The  explorations  disclose  the  existence  of  the  A'eiu  for  a 
distance  of  about  500  feet.     *     "     ^'' 

West  Vahh — One  hundred  feet  Avest  of  the  midjle  A'cin  or 
300  feet  Avest  of  the  east  vein,  Ave  come  to  the  AA'est  Aein. 
This  has  been  opened  '■'  *  "'  by  the  O'Neil  shaft,  which 
was  sunk  to  a  depth  of  46  feet  betAveen  tAvo  good  Avails,  dip- 
ping about  00  degrees  Avest,  and  said  to  l)e  about  three  and 
one  half  feet  apart.  Adding  the  ore  on  the  dump  to  that 
ship]ied,  I  make  the  Avidth  of  the  vein  about  the  same.  The 
ore  here  Avas  of  good  grade  shoAving  free  gold  as  in  the  middle 
A'ein,  but  the  bottom  of  the  shaft  is  tilled  Avith  slaty  material 
carrying  but  little  (piartz.  Several  pits  shoAV  the  continuity 
of  the  vein  150  feet  to  the  south.  Crossing  a  swampy  h.ottom, 
a  second  shaft  is  sunk  400  feet  to  the  north,  in  Avhicli  a  depth 
of  40  feet  AA-as  attained  (A  20).  In  this  shaft  a  fault  was  dis- 
closed. *  *  "•■'  Two  other  openings  are  made  on  the  same 
vein,  one  070  feet  north  of  the  C  shaft,  and  the  other  still  470 
feet  beyond  (sq.  A  31).  The  latter  is  just  Avest  of  the  north- 
ernmost outcrop  of  the  east  vein  and  about  200  feet  to  the 
west.  The  first  of  the  shafts  (A  27)  is  but  little  more  than  a 
large  prospect-hole,  but  shows  the  A'ein  in  quartz.  The  second 
shaft,  marked  HaAvkeye  shaft,  is  about  35  feet  deep,  with  a 
strong  Avesterly  dip,  the  foot-Avall  flattening  rapidly  and  cut-

Stn(c((in'  and  diameter  of  the  Vein. —  *  *  *  From  all 
the  facts  collectpd,  it  would  be  more  correct  to  describe  this 
group  of  mines  as  a  mineralized  belt  than  a  series  of  true 
tissure-veins.  In  none  of  the  siiafts,  if  we  except  the  O'Neil 
shaft,  is  there  any  evidence  of  the  smooth  boundary-walls 
with  clay  seams  and  ])olished  faces,  although  there  is  an 
abundant  evidence  of  great  motion  in  the  fissures. 

*  *  *  *  The  extent  of  the  veins  north  and  south,  as 
seen  on  the  property  (3100  feet),  and  their  recurrence  again 
at  other  pf)ints  both  north  and  south,  leave  but  little  if  any 
doubt  of  their  ])ermaneuce  in  depth.  In  width  the  ore  is 
variable.  In  no  case,  if  we  except  the  west  and  middle  veius, 
has  its  true  width  been  determined.  No  hanging-wall  has 
been  found  in  the  deep  or  Tuttle  shafts,  and  it  is  ({uestion- 
able  whether  the  same  is  not  the  case  in  the  A  shaft,  yet  we 
know  the  quartz  to  be  18  feet  thick  in  some  portions  of  the 
deep  shaft,  and  10  feet  thick  in  the  Tuttle  shaft,  while  the 
probabilities,  as  shown  in  the  sketches  of  these  shafts  on 
Map  1,  are  that  it  will  prove  to  be  20  feet  thick  or  over  in 
both  cases.  In  the  west  or  middle  veins,  the  thickness  is 
probably  from  three  to  ioxxr  feet. 

Character  of  the  Ores. — The  ores  consist  chiefly  of  a  quartz 
gangue,  more  or  less  mixed  with  varying  (quantities  of 
calc-spar,  the  whole  mass  being  occasionally  mixed  with 
masses  and  fragments  of  talcose  slaty  matter.  The  asso- 
ciated minerals  are  mispickel  or  arsenical  pyrites  of  iron  in 
large  quantities,  carrying  gold  both  free  and  in  combinations, 
with  occasional  patches  of  iron  and  copper  pyrites,  red 
hematite,  and  mica.  The  gold  is  sometimes  visible.  *  *  * 
The  mi:^eral  also  penetrates  the  slaty  fragments,  and  the 
presence  of  these  does  not  impoverish  the  ore,  but  seems,  as

in  many  other  iniuing  districts,  if  any  thing,  to  improve  its 
quality. 

Qttanfifj/  of  Ore. —  *  *  »  *  The  amount  which  has

1000  tons  are  still  on  the  dumps.     '^     *     -     *     '^ 

I  estimate  the  amount  of  ore  in  sight  as  follows  : 
*  *  *  *  * 

'•  A  ■'  to  Tuttle  Shaft 145  x  40  x  10  feet  =   ,"8,5()0  cubic  feet,  or  6,850  tons.

Total  tons  ill  sight 21,470 

This  estimate  is  based  on  ten  cubic  feet  to  one  ton,  which 
is  the  extreme  alhnvance.  If  calculated  at  twelve  cubic  feet 
to  one  ton,  the  result  would  be  17,891  tons. 

The  developments  made  render  it  pr<ihabh,  however,  that 
more  or  less  ore  will  be  found  between  the  present  explora- 
tions in  the  "A"  and  deep  shafts  and  in  the  ground  below  the 
"A"  and  Turtle  shafts.  This  quantity  I  should  estimate  as 
follows  as  an  extreme  limit : 

"  A  "  to  deep  shaft,  240  x  100,  with  an  allowance 

of  one  half  for  barren  ground  ^ 12,000  tons. 

Below  "  A  "  and  Tuttle  shafts,  150  x  GO  x  V°,  with 

the  '^amc  allowance  for  waste ' 4,500  tons. 


16,500  tons. 

*  *  *  *  Probable  ore-yield  from  the  three  veins  (prin- 
cipal) on  the  (ratling  ])ropertv  for  505  feet  in  length  and  100 
feet  deep,  I  estimate  in  this  report  82,750  tons.     *     *     «• 

The  puiv  gold  in  the  average  ore  would  be  about  $1.3.06 
per  ton,  witli  some  silver,  the  latter  being  lost  in  the  chlori- 
nating process.     *     ^-     * 

Tola!  cost  of  mining,  milling,  etc.,  per  ton  |  given  in  full 
detail),  is  a  shade  over  f3  per  con,  and  urices  of  labor  are  all 
estimated  high  ;  a)\  allowance  of  §3.25  per  ton  seems  ample. 


51 


Net  value  of  Ore  per  Ton. — Ah  we  arrived  at  an  average 
value  of  $13.0G  per  ton  for  the  ore,  and  allow  ten  per  cent 
wastage  in  treatment  by  chlorination  ($1.30;,  the  net  value  of 
the  ore  per  ton  would  be  i?13.0G,  h's.s  $1.30,  /es.s  $3.25,  or  $8.50 
per  ton.  This  would  make  the  net  value  of  the  reserves  or 
ore  in  sight  21  470  t(y.is,  at  $8.50,  or  $182,495,  if  estimated 
at  ten  cubic  feet  to  one  ton.  '•'  *  *  The  net  value  of  min- 
ing probabilities  to  a  depth  of  sav  100  feet  on  the  east  vein 
(by  a  length  of  about  375  feet),  say  16,500  tons,  at  $8.50  per 
toiti,  or  $140,250.     ^     *     * 

With  every  thing  complete,  I  estimate  the  monthly  net  in- 
come from  100  tons  daily,  at  $8.50  per  ton,  to  be  $25,500;  or, 
to  make  allowance  fr)r  all  contingencies,'  say  $20,000. 

*  *  *  The  presence  of  so  large  a  number  of  men  would 
almost  necessarily  result  in  tlie  erection  of  quite  a  village, 
and  by  the  opening  of  a  judiciously  managed  store,  the  com- 
pany might  add  considerably  to  its  income,  and,  if  awake  to 
its  interests,  could  concentrate  the  trade  of  a  large  district.

In 


Opinion  of  Mr.  X.  B.  Walker. 

The  following  extract  from  a  private  letter  written  by  Mr. 
Is.  B.  Walker,  of  this  city,  is  given  as  expressing  the  opinion 
of  a  careful,  conservative,  and  clearsighted  business  man, 
who  has  had  much  experience  in  visiting  and  investigating 
mining  enterprises  in  all  parts  of  the  West ;  though  with  all 
this,  Mr.  Walker  does  not  profess  to  be  a  mining  export  or 
engineer : 

Dear  Siii :  Your  telegram  was  received  at  Torontf)  on  the 
1st  inst.,  suggesting  ray  visiting  the  Canada  ('onsolidated 
Mines.  I  prevailed  on  Francis  to  accompany  me.  We  were 
fortunate  in  learning  at  Belleville  that  Both  well  was  still 
about,  and  obliged  to  remain  over  till  after  the  7th  inst. 
Francis  left  us  on  Saturday  for  Montreal,  but  before  doing  so 


33 


T 


went  with  me  over  the  property,  and  into  the  deep  shaft  to 
the  bottom,  and  through  the  70-foot  levels.  Since  he  left,  I 
have  been  over  the  property,  and  examined  the  various 
exploring  pits  with  Eothwell,  Gen.  Tuttle,  and  Capt.  O'Neil, 
respectively,  and  feel  quite  familiar  with  the  ground,  and 
capable  of  forming  an  opinion  for  myself,  or  at  any  rate  of 
drawing  comparisons  between  it  and  other  properties  which 
I  have  examined  in  several  mining  sections  in  the  West.  The 
local  conditions  are  superior  to  any  I  have  ever  s».en,  as  I 
can  tiiink  of  no  cultural  adi'cintages,  desirable  i:i  a  mining- 
camp,  that  are  here  wanting.  The  Moira  River,  with  its  ine: 
haustible  supply  of  pure  water,  is  of  inestimable  value  and 
capable  of  furnishing  all  the  motive  power  that  will  ever 
be  required  to  run  any  machinery  you  will  need,  for  nine 
months  of  the  year,  on  the  property.  As  fine  cord-wood  as 
I  ever  saw,  Capt.  O'Neil  told  me  he  bought  just  as  I  saw  it 
on  the  pile  for  $1.25  per  cord  at  the  mill,  and  I  saw  plenty 
of  the  same  kind  of  wood  growing  on  the  property  of  the 
Company. 

"Wood  and  water "  are  two  primary  objects,  the  first 
thing  that  I  ask  for  as  local  conditions  in  a  mining  region  ; 
without  these  I  want  nothing  to  do  with  a  mine.  Our  first 
lessons,  you  know,  are  the  most  lasting  and  impressive ;  my 
first  experience  was  in  Arizona,  then  in  Nevada.  I  have  paid 
50  cents  for  water  for  myself  and  m  ule  in  Arizona,  there  being 
none  within  12  miles  that  my  mule  would  drink  ;  and  had 
the  Mexican  demanded  $5,  I  should  have  been  obliged  to 
pay  it. 

Relative  to  the  mines,  I  have  no  hesitation  in  stating  that 
I  think  the  property  very  valuable  and  capitalized  at  a  very 
low  figure.  I  have  never  seen  better  surface  indications,  and 
wherever  work  has  been  done  the  veins  have  been  found 
remarkable,  regular  in  their  course,  and  the  ore  of  uniform 
character.  From  the  water  shaft  to  the  spring  bejond  the 
Tuttle  shaft  on  the  east  vein,  I  feel  quite  confident  there  is 
a  "miner's  certainfy"  (a  word  coined  by  Louis  Janin)  of 
700  feet  in  length,  200  feet  in  depth,  and  5  feet  wide ;  thia 


53 


alone  would  yield  70,000  tons  ;  fit  a  net  profit  of  only  $5  per 
ton  would  give  $BGO,000. 

While  the  amount  of  work  that  has  been  done  on  the 
'middle"  and  "  west '"  veins  is  less  extensive  than  that  whicli 
has  been  done  on  the  "  east  "  vein,  yet  it  has  been  sufficient 
to  justify  the  expenditure  of  any  reasonable  amount  of  capital 
to  thoroughly  open  them,  and  would,  in  my  opinion,  be 
regarded  in  the  "West  as  Avorth  all  you  ask  for  the  entire 
pr(j])ertv.  The  fact  that  these  veins  can  be  explored  from 
the  '200-foot  level  of  the  "  east "  vein  by  drifting  some  150 
feet  toward  the  west,  at  a  very  trifling  expense,  is  a  matter  of 
very  great  importance. 

The  thorough  and  exhaustive  manner  in  which  the  prop- 
erty has  been  explored,  and  the  ore  tested  by  working  pro- 
cess, leaves  in  my  mind  no  room  for  a  doubt  that  the  prop- 
erty otfers  superior  inducements  as  a  legitimate  investment, 
unequaled  by  any  gold  mining  company  I  have  ever  had 
brought  to  my  notice. 


Extract  from  a  Letter  Irij  Mr.  Armitage  n/iortes,  3Iinhi(j  Engineer, 
Quebec,  dated  Deceihher  ith.  1880. 

Mr.  Rhodes  has  had  much  practical  experienne  iu  mining,  and  during  the 
past  year  has  had  charge  of  the  Victoria  lead  mine  at  Saulte  Ste.  Marie,  Ont. 
A  large  number  of  shares  of  the  stock  have  been  taken  by  himself  and  friends. 

I  visited  the  mines  of  the  Canada  Consolidated  Gold  Min- 
ing Company  last  month,  in  order  to  see  for  myself  if  the 
mines  were  as  re[)resented.  It  is  needless  for  me  to  enter 
into  any  particulars  after  so  many  reports  have  been  brought 
before  the  public  i)y  experts  of  such  high  authority.  Suffice 
it  to  say,  that  the  ore  in  sight  far  exceeded  my  anticipations, 
both  in  quantity  and  quality.  The  situation  of  the  mines  and 
dip  of  the  various  veins  are  all  most  favorable  to  inexpensive 
mining. 

The  deepest  shaft  was  about  150  feet,  in  Avhich  a  gang  of 
men  were  working  at  the  time.  The  ore  appears  t(j  improve 
in  quality  as  they  go  down.     I  found  tpiite  a  show  of  free  gold

in  difterent  plac;s,  and  ore  in  abundance  everywliere.  There- 
fore, on  my  return  home,  I  did  not  hesitate  about  purchasing 
stock  for  myseli,  besides  {giving  a  favorable  reply  to  the  many 
inquiries  I  had  from  parties  proposing  to  invest.  I  consider 
it  as  safe  an  enterprise  as  it  is  possible  for  any  mine  to  be. 


Extract  fro  III  a  Private  Letter  hy  Mr.  Adolf  Tides,  dated  Novem- 

l>er  2Wi,  1880. 

Mr.  'I'hies  spent  three  mouths  on  the  properf^j,  iu  charge  of  the  assaying 
and  milling  of  the  ores,  from  February  to  May,  1880.  and  is  tlierefore  thoroughly 
familiar  with  the  intrinsic  value  of  the  property  and  the  facility  with  which  the 
ore  is  treated. 

I  am  very  glad  indeed  to  see  from  the  EiKjineerlng  and 
Miuin.fi  Journal  that  the  stock  is  taken  so  rapidly,  though  I 
do  not  Avonder  at  this  at  all,  because  you  have  offered  it  so 
far  below  its  value.  I  was  highly  pleased  with  Mr.  RotliAvell's 
report,  and  any  one  who  has  read  the  same  and  is  still  an  un- 
believer, may  take  a  trip  to  the  mines  and  satisfy  himself ;  and 
he  will  have  to  add  a  good  deal  more  to  the  value  of  them 
than  Mr.  Kothwell's  estimate. 

There  is  no  mining  enterprise  on  this  continent  Avhicli 
offers  surer  returns  than  the  Canada  Consolidated  Gold  Min- 
ing Company. 


Report  1)1/  Walter  Shaidij,  Cir'd  EH'/lncer,  Moidreal,  Quebec. 

MoNTEEAL,  January  17,  1881. 

KicHAiii)  P.  RoTHWELi.,  Esq.,  Minlwi  Engineer,  New  York: 

Deak  Silt  :  I  have  pleasure  in  conveying  to  you  my 
impressions  of  the  Marmora  Gold  Mines,  forming  the  prop- 
erty of  the  Canada  Consolidated  Gold  Mining  (company,  as 
gathered  from  my  visit  to,  and  examination  of,  the  ground 
and  workings  last  month. 


00 


The  situ.ation  of  the  property  iu  aifordiiig  every  possible 
facility  for  cheap  workiiijif  is  probably  not  to  be  equaled  Ijv 
that  of  .any  important  <;()ltl  mine  on  this  continent. 

Most  of  the  ^reat  mines  are  to  be  looked  for  in  regions 
difficnlt  of  access,  where  labor  has  to  be  imported  and  hijj;hly 
paid  for  ;  where  even  the  sim})lest  necessaries  of  life  have  to 
be  bronu;ht  from  afar,  and  at  great  expense ;  where  fnel  is 
commonly  a  scarce  and  precious  article,  and  where  even 
water  has  to  be  paid  for  by  the  inch. 

The  Marmora  mines  lie  in  the  midst  of  a  highly  pro- 
ductive wheat-growing  and  catth^-raising  country,  where 
provisions  and  all  the  other  recpiisites  of  "  living  "  are  as 
abundant  as,  and  cheaper  than,  in  New  England  or  New  York, 
The  County  of  Hastings,  of  which  the  Townshi})  of  Mnrmora 
is  a  subdivision,  is  intersected  bv  macadamized  highwavs  and 
railwavs.  One  of  the  former  extends  from  the  city  of  BeHe- 
ville,  on  Lake  Ontario,  to  the  mine,  and  there  is  a  railway 
station  within  ten  miles. 

In  respect  of  geogra])hical  ])osition,  measured  by  time, 
relatively  to  the  grt^at  business  centers  of  Canada  and  the 
adjoining  States,  Marnioi'a,  Iviiig  /»:{  miles  buck  from  Belle- 
ville, is  distant  from — 

Toronto,  about  10  hours  ; 
Montreal,  about  14  hours  ; 
New  York  or  Boston,  ?»()  hours. 

Fuel-wood  of  the  choicest  description  can  l)e  bought  at 
the  mine  iov  J^l.25  per  cord  of  l!28  I'ubic  feet,  Avhile  the  River 
Moira,  ])assing  through  tlu^  property,  afl'ords  abundant  su])])ly 
of  water  for  all  ordinary  mining  uses  in  all  seasons,  and  (witii 
30  feet  fall)  ample  power  for  driving  machinery  for  nine 
months  in  the  year. 

The  great  Hiunestake  Mining  Company  (gold),  in  the 
"  Black  Hills"  ccmntry,  i)ublishes  the  following  statement  for 
the  two  years  and  nine  months  ending  with  August,  1880 : 

Total  tons  of  cn-e  trrushed,  278,283. 
Net  bullion  extracted,  .i;l,88y,283.98. 


I 


56 


Total  working  expenses,  $959,825.98. 

The  cost  of  plant,  stiinip-niills,  etc.,  was  $455,210.10. 

And  dividends  paid  in  same  two  years  and  nine  months, 
!5;()00,0()0. 

This  great  result  was  obtained  from  ore  yielding,  net,  only 
about  $6  j^„"y  per  ton. 

The  working  expenses  per  ton  of  rock,  averaged  SB,'*,,",,. 

Comparing  prices  for  labor  and  "  supplies"  of  all  kinds 
at  the  Honiestake  mine  Avitli  what  w^e  know  will  ])e  ruling 
rates  in  Marmora,  and  allowing  for  any  probable  increase 
over  present  rates,  the  relative  cost  of  extracting  the  bullion 
in  the  two  localities,  supposing  the  ores  to  be  identical  in 
character,  would  be  as  follows  : 

Homestake.  Marmora. 

Labor  of  mining  and  milling,  per  ton $1  40  $0  70 

Shafts  and  dead-work 30  20 

Machine  and  blacksmith  shops  and  all  else.  71  47 

Fuel 28  10 

Water 11 

All  other  "  supplies" GO  50 

Whole  cost,  per  ton,  of  rock $3  4G  $1  97 


And  this  comparison,  so  widely  in  favor  of  Marmora 
"  facilities,"  does  not  take  into  account  the  large  saving  to  be 
effected  there  by  the  use  of  water-power  for  the  greater  part 
of  the  year  as  against  steam-power,  with  wood  at  $4.75  per 
cord  ,dl  the  vear  round  at  the  Homestake  mine. 


The  Homestake  ore  yields,  net,  as  stated  above,  $( 


1 0  u  F*^^ 


ton. 


The  average  of  108  assays,  from  108  five-ton  samples  of 
Marmora  rock,  shows  $13.37. 

These  tests,  chiefly  from  your  own  sampling  and  assays, 
must  be  taken  as  having  been  very  safeJy  made  ;  for  I  find 
reports  from  nine  other  well-known  mineralogists  giving  far 
higher  results.  The  average  of  all  the  tests  made  seems  to 
leave  no  room  to  doubt  that  the  per  ton  value  of  the  ore  is 
fully  $18V\ A,.

This  fifreat  result  was  obtained  from  ore  yielding,  net,  only 
about  $6j^„"y  per  ton. 

The  working  expenses  per  ton  of  rock,  averaged  -S3  j*,,'',,. 

Comparing  prices  for  labor  and  "  supplies"  of  all  kinds 
ac  the  Homestake  nnne  with  what  we  know  Avill  be  ruling 
rates  in  Marmora,  and  allowing  for  any  probable  increase 
over  present  rates,  the  rehative  cost  of  extracting  the  bullion 
in  the  two  localities,  supposing  the  ores  to  bo  identical  in 
character,  would  be  as  follows  : 

Ilomestako.  .Marmora. 

Labor  of  mining  and  milling,  per  ton $1  40  $0  70

All  other  '•'  supplies" GO  50 

Whole  cost,  per  ton,  of  rock S3  4G  $1  97 


As,  however,  the  Marmora  ore  requires  to  be  roasted  and 
chhrrinated,  the  cost  will  be  increased  ;  althougli,  since  only 
the  concentrates,  or  say  one  ton  in  three,  will  be  roasted,  and 
only  one  ton  in  four  will  }w  chlorinated,  the  total  cost  of 
mining,  n)illing,  etc.,  reduced  to  the  ton  of  ore  as  extracted 
from  the  mine,  will  still  not  exceed  from  $3  to  $3.50  per  ton, 
or  not  move  than  at  the  famous  Homestake,  Avhose  ore  vields 
only  SG.HO  per  ton,  and  where  fuel  is  $4.75  per  cf)rd. 


'/- 


iiigiicr    ifsuits. 


xne  average  oi  an  me  tests  made  seems  lo 
leave  no  room  to  doubt  that  the  per  ton  value  of  the  ore  is 
fully  $18y\,V.

As  fin  offset  to  tlio  lii^rli  prieos  of  Ijilx.v  !iii(l  .supplies  in  tlie 
VA'.ick  Hills  rooion,  the  Homestuke  ore  is  adnutted  to  be  "soft 
iuul  friable,  bivuking  into  small  pieces  after  being  shattered 
by  blasting,  and  is  readily  crusln'd  in  the  mill.  It  is  in  the 
highest  d(>nree  a  tree-miliing  ore,  and  is  rea.lily  amalgamated, 
the  gold  it  contains  being  mostly  coarse  and  easily  saved  in 
tlie  l)atteries." 

These  are  large  advantages,  and  did  the  Marmora  rock 
possess  them  in  .-.lual  degree,  the  value  of  the  proi)erty  Avould 
be  almost  iiicalcnlable.  None  of  the  veins  as  yet  exposed, 
how(>vt>r,  mine  as  easily  or  will  "mill"  as  freely  as  the 
"  Homestake"  ores.  On  the  contrary,  they  are  roasting  ores, 
and  the  cost  of  treatment  is  consequently  much  increased. 

Th(^  counterbalancing  advantages  of  Marmora  are  to  be 
sought  for  in  the  greater  richness  of  the  ore,  almost  three  to 
one,  and  in  the  immensely  greater  wo)king  facilities  in  respect 
of  labor,  materials,  and  water-poAver,  and  I  confidently  predict 
that  the  "  c(mnterbalancing"  \vill  prove  so  entire  and  com- 
plete as  to  place  the  Marmora  in  the  front  rank  of  paying 
gold  mines. 

But  a  small  p..rt,  comparatively,  of  the  Canada  Consoli- 
dated (lold  Mining  Company's  proi)erty  has  as  yet  been 
"  proved  ;"  l)utyour  estimate  of  the  value  of  the  "ore  in  sight" 
appears  to  me  to  be  not  overstated  at  .ii>575,000;  and  with 
proper  application  of  capital  and  skill,  the  enterprise  can  not 
fail  of  proving  a  notable  success.  W.   Shanly.
